Wavelength Division Multiplexed Networks with Minimal Conversion and Switching

摘要

Optical network architectures that employ wavelength division multiplexing are proposed and evaluated at two layers. The first layer dynamically switches optical connections. Network architectures at this layer allow a limited amount of wavelength switching by the optical connections. Network topologies and efficient resource allocation algorithms are proposed and evaluated. The second layer dynamically switches electronic traffic streams and multiplexes them onto the optical connections. Network architectures at this layer provide maximal switching capability, but at significantly reduced equipment costs.
